Application November 22, 1944, Serial No. 564,588

Clams. (01.-2'77-42) My present invention, in its broad aspect, has

to do with improvements in carburetor air intake and vaporizer devices, wherein controlling means are provided between a primary and secondary air intake to the end thata more desirable regulation of the amount of air admitted is obtained. My present invention has a movably mounted telescopic funnel, and baille plates, and inner and outer chambers with a primary air intake tube located in the inner chamber with the conical portion thereof extending through the opening in the bottom of the casing. In connection with my present device, attention is called to my prior Patent #2,029,210 granted January 28, 1936, on Carburetor air intake and vaporizer.

My present device can be applied to conventional types of internal combustion engines without appreciable modiiication and is designed to improve the character of the explosive mixture. The control rods of my present invention permit the primary air tube and the air adjusting cone to be adjusted upwardly or downwardly to regulate the ow of air, and adjustment of the pri mary air tube upwardly acts through a rocker arm and push rod to impart corresponding downward movement to the telescopic tube.

Other and equally important objects and advantages of my invention will be apparent from the following description taken in connection with the accompanying drawings, but it is to be understood that changes in form, size, shape, construction and arrangement of parts can be made without departing from the spirit of my invention or the scope of the appended claims.

In the drawings wherein I have illustrated a preferred form of my invention the figure is a vertical section wherein the various operating parts are shown.

In the drawings wherein like characters of reference are used to designate like or similar parts throughout the several views:

The numeral I designates the cylindrical outer casing which has an outwardly flared upper portion E, and a conical bottom wall 3 communiu eating with a connection 4 to the intake manifold of the engine. Mounted in the casing I and spaced from the inner wall thereof is a cy1indrical member 9 having an inner chamber 5 and an outer chamber 6 between the member and the wall of the casing. This member is supported by brackets 1. The outer chamber 6 is open at the Vtop and closed at the bottom, and the inner chamber is open at the bottom and closed at the top. Upper downwardly sloping baies 8 are formed on cylindrical member 9, and inwardly and horizontally extending down baffles I0 are formed on the casing I so that air takes a cir-V cuitous path. A telescopic cylindrical tube II, operates ybetween the inner and outer walls I2.- and I3 in the member I). An inner cylinder I5l is--provided in chamber 5 in spaced relation to member il.. Cylinder 9 is anged at its upper end It to form with member 9, tube I I and cylinder I5, a packing gland. Cylinder I5 is flanged at IG at the bottom to form an abutment for spring Il, the upper end of which bears against the connecting web I8 between tube I I and an inner tube i3. An air adjusting cone 2D has a anged top 2E seating on web I8 and bolted as at 22 to the arm 23 of controlling rod 24. Controlling rod 2t has a pin 25 operating in the slot 25 in the support 2'( on casing l. A push rod 28 is threaded as at 29 and extends freely through arm 23 and has an adjusting nut that engages the upper surface oi' the arm 23. A rocker arm 3I engages the push rod 28 and is pivoted to the standard 32, and has its opposite end connected as at 33 to the web i8 on tube II.

The lower end of rod 28 is attached as at 34 to the funnel 35 of the primary air intake, so that adjustment of the nut 30 on the rod 28 adjusts both the primary air intake and the secondary air intake represented by tube I I and chamber 6. Thus the movement of the nut 30 on the rod 28 will cause the arm 23 for the cone 23 to move upwardly according to the position the nut SII is on the rod 28. Should the rocker arm 3l further move the funnel 35, the arm '23 can move further, should additional air be needed in the operation f of the device. In connection with my present invention, it will be further noted that funnel 35 is now adjustable whereas in my prior patent it was fixed.

From the foregoing, it is believed that the operation and advantages of my invention will be apparent, but it is again emphasized that interpretation thereof should only be conclusive when made in the light of the subjoined claims.

I claim:

1. An air intake and vaporizer for carburetors, comprising a plurality of telescoping cylindrical members having their walls interitting to form inner and outer chambers and constituting a secondary air intake, an air adjusting cone supported by said members, a casing secured to and partially surrounding said members, a funnel-like member engaging the lower portion of the casing and constituting the primary air intake, a spring between the cylindrical members, and a rocker arm mounted on one of said members having adjustable connection between the telescoping members and funnel.

Y2. An air intake and vaporizer for carburetors, comprising a plurality of telescoping tubes or cylindrical members having their walls intertting to form inner and outer chambers, a funnellike member adjustably mounted in said inner chamber, a casing enclosing said members on which the funnel-like member is supported, brackets on the casing connected with the telescoping cylindrical members, an adjusting means including a rocker arm mounted on said members whereby adjustment of the funnel adjusts the tubes, a spring acting between the tubes, and a plurality of baflie plates formed on the tubes and casing and extending into the chamber between the tubes and casing.

3. An air intake and vaporizer for carburetors, comprising double walled tubes, reversed and relatively telescoping, packing between the tubes, a spring mounted within and acting on the tubes, a casing partially enclosing and supported by the tubes, a funnel constituting a primary air intake engaging the casing below the tubes, and adjusting means including a controlling rod and a rocker arm connected with the tubes and the funnel to adjust the relative positions of each.

4. The invention as described in claim 3 wherein an air adjusting cone is mounted on said tubes, and wherein the tubes are provided with an upper baille plate which is downwardly inclined and the casing with lower baie plate which extends horizontally from a wall of the casing to provide a tortuous path for air entering the device.

5. The invention as described in claim 3 wherein the casing has an outwardly flared flanged top and a conical bottom wall, and a bracket means is attached to the flange of the casing and engages the downwardly inclined baille on the outer te1escoping cylindrical member.
